Science/Nutrition experts: Can a pound of food have more than 3,500 calories?

Question

They say you will lose a pound of fat if you burn 3,500 calories more than you take in. In this world of processed foods, is it possible for a pound of food to have more than 3,500 calories? This question is actually more thought provoking than it appears. Thanks in advance.

Answer 1

I believe a gram of fat provides approximately 9 kcal of energy, so at 9 kcal/gram (453.6 gram/lb.), one pound of fat would provide 4082.4 kcal of energy , or 4082 food "calories." Interesting question that--I never tried to figure it before!

Answer 2

Well... let's convert this to units more popularly used for food. 3500 Calories per pound is a little more than 218 Calories per ounce. The capital C is important, because it distinguishes dietary calories from actual calories - a Calorie is actually a thousand calories, or a kcal.

There are foods that are more than this target number, but not a lot of them. If you could drink pure canola or olive oil, for example, they have 240 Calories per ounce. Ick. If you ate an ounce of pure dietary fat, it would have 255 Calories per ounce (ick on that one too).

Most candies have only 100-150 Calories per ounce. Chips are usually 150 per oz. Even liquor is only 64 Calories per ounce. Nuts, on the other hand, are usually 160-200.

Answer 3

The weight of food has nothing to do with the calories it contains. Carrots are heavy but low in calories.

A calorie is the amount of energy it takes to heat an amount of liquid one degree, that's all.

You must burn 3500 of those calories to lose 1 pound of body fat, unless you pick a thermogenic diet like Kimkins. Members lose weight much faster than 3500 = 1 lb allows.

Answer 4

A pound of human fat requires the human to burn 3,500 calories but that has nothing to do with how calorie dense foods are.

I'd bet most candies have more than 3,500 calories in a pound... or that a pound of sugar has more than 3,500 calories....

Answer 5

youre probably meaning the kilo-calorie right.. because most foods would definitely have 3,500 "calories".
well.. fats contain a energy density of 9 kcal/g
1 pound is approx. 500 g so 9 * 500 = 4500 kcal - so maybe?
if it was all fat...

food component energy density in kcal/g
fat 9
ethanol (alcohol) 7
proteins 4
carbohydrates 4
organic acids 3
Sugar alcohols (sweeteners) 2.4

hope it helps

Answer 6

It is surely possible for a food to contain more than 3500 calories...

Now its also impossible for your body to retain a pound of fat if you BURN 3500 UNUSED calories..

Food doesnt equal Fat in equal terms...your body doesnt equate 3500 calories to 1 lb of fat. It equates a lil here and there, whatever your body didnt burn off and is left behind.

Answer 7

Absolutely a pound of food can have more than 3500 calories. Body fat needing 3500 calories worth of expenditure to drop a pound, isn't related to the number of calories per pound of food. A high cocoa butter and extra sweet pound of chocolate will deposit more than one pound of fat in your body, then it would take 3500 calories of fat burning exercise to burn one pound of that.
